  • GSM Global System for Mobile Communication
  • the invention and the underlying system 2 can instead use any type of electronic reading device, such as an electronic pen, an electronic mouse, or a hand scanner.
  • the system 2 includes six different entities, including the electronic pen 10, electronic pen client 22, a control node 24, a name server 26, a base translator 28, and an application server 30.
  • these various devices are described and depicted separately, it is also possible to combine two or more of the entities into the same device (e.g., the electronic pen 10 and electronic pen client 22 can be contained in the same device) .
  • the electronic pen 10 is responsible for detecting positions on the address pattern, producing actions, and sending information to the electronic pen client 22. In addition to being able to leave pen markings, some electronic pens can also have the ability to produce other types of output, such as sound, vibration, or flashing lights.
  • the electronic pen 10 includes a memory for storing a current grid, which comprises information relating to an area of the address pattern that is near the most recently detected position of the electronic pen 10. When the electronic pen 10 is loaded with the current grid, it knows what actions to take based on the positions that are read from the address pattern. When the electronic pen 10 is first turned on or when it moves to an area outside of the current grid, the electronic pen 10 must first request a new grid description before it can continue processing information. In such a situation, the electronic pen 10 requests a new grid description from the electronic pen client 22.
  • the electronic pen client 22 can be located in a mobile station 14, in a PDA, in a desktop or portable computer, in the electronic pen 10 itself, in a server somewhere on the Internet, or in another device.
  • the electronic pen client 22 serves as the center of communications in the overall system 2.
  • the electronic pen client 22 receives new grid requests and action requests from the electronic pen 10 and responds to these requests by contacting an appropriate entity within the overall system 2 to properly respond to the request from the electronic pen 10.
  • the electronic pen client 22 can store the application and/or any corresponding data received from the electronic pen 10 to facilitate processing and use of the application.
  • the name server 26 is used for translating a detected position on the address pattern into a Uniform Resource Location (URL) associated with that position. Different portions of the address pattern are assigned to different applications. Neither the electronic pen 10 nor the electronic pen client 22, however, is aware of all of the different applications and the particular areas assigned to each application. Thus, when the electronic pen 10 detects a new or unknown position, it forwards the position information to the electronic pen client 22, which in turn sends the information to the name server 26. The name server 26 then identifies an application associated with the received position and retrieves a URL where a description of the particular application can be found. The retrieved URL can then be used by the electronic pen client 22 to retrieve the application description.
  • URL Uniform Resource Location
  • the name server 26 can comprise a global name server that keeps track of a location, in the form of URLs to local name servers, where more information can be found about different addresses in the pattern.
  • each local name server can use other local name servers to obtain the necessary information, i.e. , to convert a position into a URL where an application description can be found.
  • the local electronic pen client should know all the paper addresses that are within a specific application or applications.
  • the base translator 28 can be used to support the services.
  • the base translator 28 might contain handwriting recognition software for converting pen actions into text or for converting pen actions into a predefined set of symbols.
  • the electronic pen client 22 can send a request to the base translator 28 along with the necessary data, and the base translator 28 can perform the requested service.
  • Another entity in the system 2 is a control node 24.
  • the control node 24 is used for responding to actions in a standardized way.
  • the control node 24 can be used to respond to certain generic functions, such as "cancel" or "submit” functions, in a consistent manner without regard to the particular application that is currently active.
  • control node 24 is used for creating streaming-like applications. For instance, some applications might require that the positions on the address pattern that are detected by the electronic pen 10 be immediately sent, upon detection, to the electronic pen client 22 for use by the application (i.e., the electronic pen 10 does not wait to transmit the position data until a complete stroke is detected or until a "send" field is touched) .
  • One example is an application that is used to control an industrial robot in a warehouse.
  • the application description that is loaded onto the electronic pen server 22 can include instructions that all positions be streamed to a control node 24.
  • the control node 24 can receive the positions in real time and can control the robot without waiting for the form (i.e., the current grid) to be completed.
  • the control node 24 can perform a real-time translation from detected positions to a responsive action, such as moving an object (e.g., a robot, a valve, etc.) or controlling a process .
  • the application server 30 is a regular web or wireless application protocol (WAP) server that supports an application associated with a particular area of the address pattern.
  • the application server 30 stores an application description and provides the application description to the electronic pen client 22 upon request.
  • the application server 30 receives input data from the electronic pen 10 via the electronic pen client 22.
  • the application description might define a number of data entry areas on a form.
  • the application server 30 stores the data or otherwise processes the data in accordance with the function of the application.

  • FIGURE 3 illustrates the protocol stacks that can be used in the case of local communications (e.g., using Bluetooth) between the electronic pen 10 and the electronic pen client 22. If, on the other hand, the electronic pen 10 and the electronic pen client 22 communicate with one another via an Internet connection, the protocol stacks depicted in FIGURE 4 will be used.

  • FIGURE 6 depicts the protocol stacks that are used when the electronic pen client 22 is located on the Internet.
  • the electronic pen 10 detects a position on the address pattern that is not within its currently loaded grid or when the electror ic pen 10 has no currently loaded grid, the electronic pen 10 initiates a new grid procedure.
  • the new grid procedure involves sending a new grid request object to the electronic pen client 22.
  • the new grid request object contains the newly detected position, a description of the actions that the electronic pen 10 can natively support, and a description of the output signals that the electronic pen 10 supports.
  • the reply to a new grid request object is a grid description, which can be provided by the electronic pen client 22 from its own internal memory or from the information provided by an application server 30.
  • the electronic pen client 22 extracts the grid description from an application description received from the application server 30.
  • the grid description should only contain action-field-types that the electronic pen 10 has indicated that it natively supports, which means that the electronic pen client 22 in some cases should convert the extracted grid description into a format that the electronic pen 10 can understand.
  • the electronic pen client 22 sends an empty grid description to the electronic pen 10, thereby causing the electronic pen 10 to unload its current grid.
  • the grid exception comprises a rectangle or other shape indicating the area around the detected position where no registered applications can be found.
  • the indicated area is as large as possible so that the electronic pen 10 and/or electronic pen client 22 know the extent of the surrounding area that is unassigned and do not have to repeatedly send requests to the name server 26.
  • the empty grid description with a grid exception causes the electronic pen 10 to unload its current grid and also informs the electronic pen 10 of an area surrounding the detected position that can essentially be ignored because its is not associated with any application.
  • the procedure that is used when the electronic pen 10 detects a new position is a find application description location procedure.
  • This procedure is used by the electronic pen client 22 to translate a detected position received from the electronic pen 10 into a URL where a description of an application corresponding to that position can be found.

Abstract

L'invention concerne un procédé et un système servant à régler, à configurer et à déverrouiller un dispositif électronique, qui utilisent un détecteur de lecture pour détecter une partie de motif d'adresse sur une surface formatée. En particulier, le motif d'adresse situé sur la surface est formaté de façon à permettre de déterminer une position sur le motif d'adresse, par la détection d'une petite partie seulement du motif d'adresse. Un processeur permet d'identifier si la position détectée du motif d'adresse se situe dans une zone de configuration du dispositif de lecture électronique ; si c'est le cas, le processeur convertit les données de position reçues du détecteur de lecture en paramètres de configuration ou en une fonction de commande du dispositif électronique. La conversion peut être mise en oeuvre, par exemple, par la traduction de la ou des positions détectées en un caractère alphanumérique. Les paramètres de configuration sont ensuite stockés dans le dispositif de lecture électronique et/ou dans un serveur associé à celui-ci, ou la fonction de commande est exécutée. Dans une autre forme de réalisation, au lieu d'une conversion des positions détectées en paramètres de configuration, on peut utiliser une conversion des positions détectées en un code de déverrouillage (p. ex. NIP ou signature) qui est ensuite comparé à un identificateur d'utilisateur mémorisé. Si une correspondance entre ceux-ci est établie, le dispositif de lecture électronique est activé ou déverrouillé.
